租金回报率计算器
快速计算房产租金回报率，评估投资价值
房产投资者常因手动计算租金回报率繁琐且易出错而困扰，本工具一键输入月租金、房价等关键数据，自动输出年化回报率百分比，帮助您快速评估房产投资价值。租金回报率是衡量房产投资收益的核心指标，计算公式为（年租金收入/房产总价）×100%。
输入金额需为正整数，空置率范围为0-100%；结果仅供参考，实际投资需考虑税费、物业费等额外成本；本工具不存储用户数据，无需担心隐私泄露。
建议计算时区分毛回报率（仅租金与房价比）和净回报率（扣除空置、维护等成本），一线城市核心地段回报率通常低于3%，而二线城市优质物业可能达5%以上。长期投资还应结合房价增值潜力综合判断。
